A method and apparatus for the automatic radiograpgicreal-time analysis of articles, in particular for pipe-plug weldings.

摘要

A method and apparatus is disclosed allowing a real-time analysis on specimens having any composition and geometry. The specimen in placed in front of a radiographic camera with a computer controlled positioning; the radiographic image is enlarged, converted into a visible image and subsequently projected onto a pick-up plane in real time, where a television camera converts the light energy contained in the beam coming from the image into an electric signal. Said signal is then digitized and it is consequently suitable to be memorized and displayed and to be subjected to all processing operations for the detection of possible defects.
